Example from class on 9/29: Search for articles on the following research question in PsycINFO:
What is the impact of moderate brain trauma on episodic memory?
Start by identifying key concepts: brain trauma, episodic memory
Search #1 Brain trauma episodic autobiographical memory
n=0 (number of results = 0)
Search #2: Adding “AND”
(brain trauma) AND (episodic) AND (memory)
Search #3: Adding new terms with “OR”: brain injury, autobiographical
(brain trauma OR brain injury) AND (episodic OR autobiographical) AND (memory)
Search #4: Phrase searching
("brain trauma" OR "brain injury") AND (episodic OR autobiographical) AND (memory)
Search #5: Adding truncation
(trauma* OR injur*) AND (brain OR head) AND (episodic OR autobiographical) AND (memory)
How do we narrow down our results??
- Add more concepts with AND (like AND amnesi*) (n=143)
- Use limits like date range, source type, methodology, age (instead of key words) and language, peer-reviewed
